DM6437 GPIO question.

Hi Cheah Hun Oon,

You can go through the "Peripheral Information and Electrical Specification"  section of the datasheet to find out which devices can be interfaced to TMS320DM6437.

Hi,

What i mean that if I want to send a pulse signal from the board to the microcontroller. But from the user guide hardware diagram, I cannot find the GPIO pin that is mention in the datasheet. Is that GPIO able to send pulse signal to a microcontroller for example a 5 Volt signal to the microcontroller input port.

Thank you.

Hi Cheah Hun Oon,

It is clearly mentioned in section 6.23 of the device datasheet that there are 111 GPIO pins GP[0:110] and you can see the pin assignment information in section 2.5.

I am just writing down the information provided in section 6.23 of the datasheet regarding the GPIO pins:

"The GPIO peripheral provides general-purpose pins that can be configured as either inputs or outputs. When configured as an output, a write to an internal register can control the state driven on the output pin. When configured as an input, the state of the input is detectable by reading the state of an internal register."

Hi Suresh K,

I understand what you are trying to tell me. But I want to know that how can I connect the board with the external hardware? Through USB port or any external part needed?
